Nice one Di! Thanks for the tips! I'm always doubting about the semicolon use and I found something on the internet that I believed to be handy (I'm not going to look for it now - too many other things to think of) but it had something to do with a list when commas where being used inside and missing words - anyway, this information I'm providing isn't very useful so just forget that or as Bru would say "Look away!"
I had to giggle about the ethicacy/efficacy and great job on finding it! Good one! I'll keep that in mind if i think something's not a word.
